To all whom t may cof/zoem.'

Be it known that I, JOSEPH K. E. TERvAs, a citizen of Finland, residing at Hancock,

lin the county of Houghton and State of Michigan, have invented certain new and useful Improvements in Reels for Picture- Machines, of which the following is a specification.

My invention relates to moving picture machines; and more particularly to the reels thereof, so that the rewinding of the film is not necessary. The object of the device is to so construct the same that after the film has been wound upon the receiving reel it may be removed therefrom and replaced upon the holder again ready for use. It unwinds from the holding reel from the center thereof and `after passing through the projecting machine winds upon the receiving reel, as shown.

In the drawings forming a part of this specification, and in which like symbols of reference represent corresponding parts in the several views Figure 1 is a side elevation of a icture machine having my invention shown t erein; Fig. 2 is a slde view of the upper reel;

Fig. 3 is the lower or receiving reel;

Fig. 4 a detail vertical, transverse section, on line 4 4 of Fig. 3; and,

Fig. 5 a detail of the supporting means for the lower reel. Y

Fig. 6 a sectional view of the belt-ring, to show the connection of the same.

1n the drawings, 1 represents the upper and 2 the lower reel. 3 is the film; 4 projecting machine through which the film is shown as passing; and 5 hub for connecting to clutch 6. The upper or paying out reel is composed of disks or plates 7 and 8, and hasinterposed between the same rollers 9 upon which the lm is adapted to feed, the same passing over rollers 10 and 11, and having its edge resting on roller 12. After passing through these rollers the film passes through rollers 13 and 14 which act to guide and hold it in its proper feeding position.

15 is a pin passing through the metal belt ring 16 which holds the film in proper position within the reel; 17 a plate upon which the rollers 9 are journale'd and 18 upper metallic ring for said rollers. 19 and 2O are recessed portions of the plate 7 to permit free operation of the hlm.

21 are threaded pins on the ring 18, the same passing through perforations 22 in the plate 7, and 23 knurled nuts on said pins to hold the parts in proper relation to each other and enable the plate 7 to be detached for the purpose of inserting the flm.

The lower or receiving reel is ccomposed of plates 24 and 25 which are adapted to be connected by means of spring catches 26, having connection 'with plate 24'and engaging slots 27 formed in plate 25. Connected to said plates are rings 28 and 29 by means of rivets 30 and 31; and said rings carry fingers 32 and 33 having angular ends 34 and 35. When the parts of the reel are assembled said fingers interlock, as shown in the drawing.

The hub 5 of the receiving reel has a central bearing 36 to connect it to its shaft and recesses 37 not necessary in this case, and is adapted to be operated by the pulley 6. 38 are upright posts on ring 29, the same having springs 39 embracing them, and clamps 40 having angular portions 41 extending under the ring 29; Said clamps are formed with perforations 42 forming bearings for the posts 39, and the clamps thus hold the film in proper position. 43 is a ring lying within the receiving reel on the plate 24, the purpose of the same being to loosen the whole film coil, so that it may be placed on the upper reell ready for use again.

The coil is lifted on said ring andr placed i in the upper reel. The ring preferably lies on the plate 25, making handling easier.

The operation of the device will be alpparent from the foregoing description. T e film is fed from the upper or paying out reel from the center of the same, and after it is wound upon the receiving reel it may be placed upon the upper reel ready for use. When, as explained, the film is'completely fed from the upper reel the belt ring is removed and placed around the film in the lower reel, when the operator grasps the same, together with the belt-ring, and places it again in the upper reel ready for reuse. rlhe belt ring runs around with the film and the film moves with the rollers, the upper reel being stationary but the lower reel revolving. l

Having now fully described my invention, what I claim as new, and desire to-secure by Letters-Patent, is

1.' ln a device of the character described, means for unwinding a coil of film from its center, a receiving reel, and a ring receiving reel, said ring adapte to lie in the v on the coil and be lifted with it to the delivery reel.

2. In a device of the character described, means for unwinding a coil of film from its center, a receiving reel, a ring in the receiving reel to loosen the hn coil and enable the same to be lifted from the reel, and slots formed in one of the side-plates engaging spring catches in the other plate for detachably connecting the sections of the receiving reel.

3.' In a device of the character described, a delivery reel having means for holding the lm in its proper position within the same and to feed and guide it, and a separable receiving reel having spring-controlled clamps impinging againstJ the iilm to hold'it in proper position and a ring by means of Whlch the film may be transferred to the `delivery reel.

4. In a device of the character described, a separable delivery reel having holding means for the film, guide rollers for the lm, a separable receiving reel to feed the film from the delivery reel, a ring in the receiving reel upon which the roll rests and by which it is controlled, fingers connected to the side plates of the receiving reel and adapted to interlock with each other, and spring catches connected with one of the plates ofI a delivery reel composed of detachable-p plates, a series of rollers disposed Within the same to feed the film, oblique rollers to deliver the film from the reel, a receiving reel to feed the film from the delivery reel, said reel formed of separable plates or disks, springs to hold the same in normal position, fastening means for the disks, and a ring upon which the coil is adapted to rest and be manipulated.

6. In a device of the character described, an upper reel for holding the film, consisting ofend plates the feeding side of said reel having a cut-away portion extending beyond its central opening, an oblique roller in the same to feed the film, a second oblique roller around Which the film is adapted to feed, a horizontal roller to support and control the edge of the film, and aplurality of substantially vertical rollers to direct the lm from -the reel, so that the lm is never twisted at an acute angle.

ln testimon whereof I ailix my signature.
